do u all mind sharing with me what are the steps needed/ the procedures to design a capacitor? Its like i've been given only its electric field intensity. And is required to find out the capacitance... mind chip in some ideas for me? btw, im designing a parallel capacitor.

relevant equations :
electric flux density, D = epsilon * electric field intensity + polarisation vector
polarisation vector = epsilon*electric susceptibility*electric field intensity

the attempt at a solution :
I've manage to solve the above and im now stuck at the Gauss' law equation...
where
E=Q/(4*pi*r^2*epsilon)
can i know what does the radius stands for? is it the radius of a charge? or the radius of the capacitor? is it fixed or we can determine it ourselves? please help...
